We present an analysis of the magnetic anisotropy in epitaxial Ga1−xMnx As thin films through electrical transport measurements on multiterminal microdevices. The film magnetization is manipulated in 3D space by a three-axis vector magnet. Anomalous switching patterns are observed in both longitudinal and transverse resistance data. In transverse geometry in particular we observe strong interpl...

The crystal structure, magnetic, electronic, and thermal properties of Mn-doped SrFe2As2 crystals have been systematically investigated. A miscibility gap is found in the system from x = 0.4362(4) to 0.9612(9). For < 0.2055(2), single holding tetragonal structure (space group I4/mmm (no. 139)) a continuously enlarged lattice parameter c, followed by phase separation with both trigonal structure...
